THELESPERMA 109 



they are produced with freedom the plant is worthy of a 

 place for edging, bedding, or for the Rock garden. There 

 is a double as well as a single variety, each about 6 inches 

 high, and a dwarf strain called Little Gem is of very com- 

 pact habit and rarely reaches 6 inches. 



THELESPERMA 



This is a small genus of Composites, and the one Hardy 

 Annual species is F. filifolia, \\ foot, yellow, with purple 

 disk. This needs the same treatment as Coreopsis, to 

 which it is allied. A hybrid between this species and 

 Coreopsis ti?ictoria is sometimes known as C. Burridgei, or 

 Cosmidium Burridgeanum. 



TRACHYMENE 



Trachymene coerulea ( UinbellifercB), known also as Didiscus 

 coeruleus, is a rather rough Half-hardy Annual from Australia. 

 It is about i^ foot high, and has blue flowers. Sow in heat 

 in Spring, and plant out after hardening the plants. 



THUNBERGIA 



Most of the Thunbergias [Acanthacece) are stove or green- 

 house climbers, but one species, T. alata, is a Half-hardy 

 Annual suitable alike for greenhouse or conservatory, or 

 for a warm place in a sheltered garden. This has yellow, 

 tubular flowers with purplish throat. In the variety aurantiaca 

 the flowers are orange-yellow with maroon centre, while 

 in alba they are white. The seeds must be sown in heat 

 in March, and each plant be given a pot to itself at an 

 early stage, with a stick to twine round. After due harden- 

 ing, planting out should take place in June. Thunbergia 

 alata makes a good basket plant if the points of growth are 

 occasionally pinched out to induce a free branching habit.
